I also have the hot rod series 56 ,I got lucky there is very little warping on the body,I was able to put the body on the chassis and with a bit of hot water,she's ad good as new,as far as the slop in the door hinges as soon as I get to were I can take pictures again ill try to get some posted of how I came up with a way to get the goods to open and close smooth,this works on all the tri five and any other kit from revell with the same type of hinge.
